Information
Introduction
The 7B52 Dual Time Base is designed specifically for
use with the 7503 Indicator Oscilloscope; however,
it is compatible with all 7000-Series Indicator Oscilloscopes.
The 7B52 features calibrated sweeps from 5 s/div to 50 ns/div
(0.5 s/div to 5 ns/div with X10 Magnification), triggering
to 100 MHz, and four display modes. Other features
include lighted pushbutton switches, 0 to 10 times
continuous sweep delay, bright base line in AUTO mode
in absence of adequate triggering signals, and an
AMPL position for X-Y operation.
Display modes include MAIN SWEEP, INTENSIFIED SWEEP,
DELAYED SWEEP, and MIXED SWEEP. In the MIXED mode,
the Main Sweep is displayed to a point selected by
the DELAY TIME MULT, after which the sweep rate is
determined by DLY'D SWEEP setting. This mode permits
sweep magnification of any point on the normal (Main)
sweep selected by the DELAY TIME MULT control.
